Telegram and several others are e2e encrypted. Metadata is the only advantage of SimpleX. It has to work.
A safe tool that doesn’t work is still broken.
To each their own. Just sharing my experience. IMO the purpose of a messenger is to message. I was not consistently successful using SimpleX. Snail mail would’ve been more reliable.
Adoption is also a key factor. I was successful in getting my entire family and most of my friends on Telegram. That means 95% of my conversations are now e2e vs before when I had to SMS those same people.
Signal was the goto for a while, but it simply does not support the feature set. Telegram literally powers our video game chats, family coordination of events, etc. It’s been a flawless and painless experience - while maintaining a *reasonable* level of privacy.
In your analogy, SimpleX is like Fort Knox and Signal, Telegram, et al. are curtains and a hedge. 😛
But that’s why we’re free and have choice. TL;DR be prepared to have spotty notifications and only use your phone to message. If those are acceptable to you, then I would say SimpleX in every other way is pretty good.
